Hello to everyone,
I've started to use openFoam for 1 month so I'm not so expert yet.
I've been running this case for about 3 days but I've still had some problems about p converge in particular about its trend that seems to be not horizontal like U plotting the residuals.

Can anyone help me about setting fvScheme and fvSolution?
Did I have done some mistakes about p boundary conditions?

NOTE: k epsilon nu values are arbitrary this is not the real simulation but just the pre-validation of the model.

NOTE: First of all I've runned the problem with a coarser Mesh, then I've refined the Mesh and I've imported the previous results in this new case.
For that reason, I've launched simpleFoam analysis for the finer Mesh with startTime of 5000.

NOTE: I wasn't able to upload also the polyMesh file (it's too big) but I checked it using checkMesh and everything seems all right, infact I've done about 15 simulation and I haven't had problems about the Mesh.

Thank you for your help
Best regards
